Question

我设计了一个配有QT设计器和PYQT5的窗.。问题在于,我无法选择任何项目、主要窗口的案文或板块,以人工方式在其他地方加以复制。这将使用户比我更容易一些。

from PyQt5 import QtCore, QtGui, QtWidgets


class Ui_MainWindow(object):
    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(800, 600)
        self.centralwidget = QtWidgets.QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.tableWidget = QtWidgets.QTableWidget(self.centralwidget)
        self.tableWidget.setGeometry(QtCore.QRect(260, 160, 256, 192))
        self.tableWidget.setRowCount(3)
        self.tableWidget.setColumnCount(2)
        self.tableWidget.setObjectName("tableWidget")
        item = QtWidgets.QTableWidgetItem()
        self.tableWidget.setItem(1, 0, item)
        self.input_gunduz = QtWidgets.QLineEdit(self.centralwidget)
        self.input_gunduz.setGeometry(QtCore.QRect(370, 70, 71, 20))
        self.input_gunduz.setObjectName("input_gunduz")
        self.label_5 = QtWidgets.QLabel(self.centralwidget)
        self.label_5.setGeometry(QtCore.QRect(220, 70, 101, 21))
        font = QtGui.QFont()
        font.setPointSize(9)
        font.setBold(True)
        font.setWeight(75)
        self.label_5.setFont(font)
        self.label_5.setObjectName("label_5")
        MainWindow.setCentralWidget(self.centralwidget)
        self.menubar = QtWidgets.QMenuBar(MainWindow)
        self.menubar.setGeometry(QtCore.QRect(0, 0, 800, 21))
        self.menubar.setObjectName("menubar")
        MainWindow.setMenuBar(self.menubar)
        self.statusbar = QtWidgets.QStatusBar(MainWindow)
        self.statusbar.setObjectName("statusbar")
        MainWindow.setStatusBar(self.statusbar)

        self.retranslateUi(MainWindow)
        QtCore.QMetaObject.connectSlotsByName(MainWindow)

    def retranslateUi(self, MainWindow):
        _translate = QtCore.QCoreApplication.translate
        MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
        __sortingEnabled = self.tableWidget.isSortingEnabled()
        self.tableWidget.setSortingEnabled(False)
        item = self.tableWidget.item(1, 0)
        item.setText(_translate("MainWindow", "trial"))
        self.tableWidget.setSortingEnabled(__sortingEnabled)
        self.label_5.setText(_translate("MainWindow", "Gündüz (kWhr):"))


if __name__ == "__main__":
    import sys
    app = QtWidgets.QApplication(sys.argv)
    MainWindow = QtWidgets.QMainWindow()
    ui = Ui_MainWindow()
    ui.setupUi(MainWindow)
    MainWindow.show()
    sys.exit(app.exec_())

守则见上文。请帮助我选择主要窗口

Copying of text does not work in the same way for every widget, because each widget type uses even radically different way to show or interact with text.

如果你想要复制QLabel的案文,你必须将其选用(通过label.setTextactionFlags(Qt.TextSelectableByMouse))。

但是,如果你想要复制QTableWidget的案文,情况就大不相同,因为表格允许与它们的项目进行互动,从而避免简单的案文选择。

显然,最简单的方法是开始编辑该项目(假定其为编辑),并选择其案文,但如果你想以其他方式这样做,则取决于how<>>。

一种可能性是使用 c+c键盘短机。为此,我们需要在表上安装一个活动过滤器:

from PyQt5 import QtCore, QtGui, QtWidgets from mainwindow import Ui_MainWindow class MainWindow(QtWidgets.QMainWindow, Ui_MainWindow): def __init__(self): super().__init__() self.setupUi(self) # install an event filter on the table widget, so that we can filter all # its event, including keyboard presses self.tableWidget.installEventFilter(self) def eventFilter(self, source, event): if event.type() == QtCore.QEvent.KeyPress and event == QtGui.QKeySequence.Copy: # check if an index is currently selected and it has text text = self.tableWidget.currentIndex().data() if text: # copy that text to the clipboard QtWidgets.QApplication.clipboard().setText(text) return super().eventFilter(source, event) if __name__ == __main__ : import sys app = QtWidgets.QApplication(sys.argv) w = MainWindow() w.show() sys.exit(app.exec_())

请注意,在上述例子中,我使用了有关,使用设计人和ui文档。页: 1

还可以确定一张表菜单,复制该表的案文:

class MainWindow(QtWidgets.QMainWindow, Ui_MainWindow): def __init__(self): # ... # use the custom context menu policy for the table widget, so that we can # connect the menu request to a slot self.tableWidget.setContextMenuPolicy(QtCore.Qt.CustomContextMenu) self.tableWidget.customContextMenuRequested.connect(self.showTableMenu) def showTableMenu(self, pos): # get the text of the index at the mouse cursor (if any) text = self.tableWidget.indexAt(pos).data() menu = QtWidgets.QMenu() copyAction = menu.addAction( Copy ) if not text: copyAction.setEnabled(False) # show the menu res = menu.exec_(QtGui.QCursor.pos()) if res == copyAction: # if the menu has been triggered by the action, copy to the clipboard QtWidgets.QApplication.clipboard().setText(text)
